ADJUSTABLE CLAMP-HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 722,935, dated March17, 1903. Application filed April 4, 1902. Serial No. 101,389. (Nomodel.)

To all 1.0700172, it may concern.-

Be it known that I, DAVID WESLEY BARR, a citizen of the United States,residing at Sioux City, in the county of Wood bury and State of Iowa,have invented a new and useful Adjustable Clamp-Horseshoe, of which thefollowing is a specification.

My invention is an improved adjustable clamp-horseshoe adapted to bereadily at tached to the hoof, adjusted to fit hoofs which vary in size,and to be readily removed from the hoof, and by means of which a horsemay be provided with sharpened calks to prevent him from slipping on icein cold weather, thus enabling a horse to be readily sharp shod withoutthe necessity of removing the old shoes.

My invention consists in the peculiar construction and combination ofdevices hereinafter fullyset'forth and claimed.

In the accompanying drawings,Figure 1 is side elevation of an adjustableclamp-horseshoe embodying my improvements, showing the same inpositionon a horses hoof in addition to the ordinary shoe. Fig. 2 is aninverted plan view of the same. Fig. 3 is a transverse sectional view ofthe same. Fig. 4 is a detail perspective view of my improved adjustableclamp horseshoe, showing the same removed from the hoof. Fig. 5 is adetail perspective view of one of the removable and adjustable calks.Fig. 6. is adetail plan view of a clamp-plate adapted for use inconnection with my improved horseshoe on an unshod hoof.

The clamp-horseshoe 1 comprises a pair of members 2, adapted to receivea hoof between them and to fit on the outside of the hoof, the bandportions 3 passing around the hoof at some distance from the bottomthereof, and" the said sections 2 are connected together at the too by atransversely-disposed plate 4., which overlaps the contiguous front endsor toe portionsof the sections 2 and is secured thereto by means ofscrews 5 or other suitable devices. The said connecting-plate 4. isprovided with a plurality of adjustingbpenings 6 to receive the screws 5and by which means the sections 2 may be adjusted laterally to narrow orwiden the clamp-shoe, and hence adapt the same to fit hoofs which varyin size. At the toe and heel portions of the sections 2 are dependingarms 7 8, respectively, the lower ends of which are turned inwardly atright angles, as atv 9. 10, to form lugs which bear under the permanentor ordinary horseshoe (1. The logs 9 are adapted to bear -under the shoeor behind the toe-calk b thereof, and the lugs 10 are adapted to bearunder said shoe a. just in advance of the heel-calks 0. Each of the lugs9 10 is provided with a threaded opening 11 to receive the upperscrewthreaded stem or shank 12 of a removable sharpened calk 13. Thelatter are preferably formed as is shown in Fig. 5and provided withshoulders 14 to bear under the lugs; but the said calks 13 may beotherwise constructed within. the scope of my invention, and I do notlimit myself in this particular.

In the upper end of the threaded shank 12 of each calk 13 is a slot 15,adapted to receive a screw-driver, by which means the shanks may bereadily removed from the lugs in the event that the calks become brokenoff from their shanks.

In order to securely clamp the heel portions of the adjustable andremovable clamp-shoe 'to the shoe or, I provide clamp-plates 16, whichare of the form shown in Fig. 3, are detachably secured to the innerends of the heellugs 10,- as by screws 17, and are provided at theirupper ends with outwardly-extending flanges 18, which bear upon theupper side of the shoe 0., between the latter and the under side of thehoof. These plates 16 are socured to the heel-lugs 10 after theadjustable clamp-horseshoehas been placed on the hoof and its toe andheel lugs engaged with the under side of the permanent or ordinary shoe.

'To enable my improved adjustable clamphorseshoe to be attached to abare hoof, I provide a foot-plate 19, such as is shown in Fig. 6, whichis of the form of an ordinary horseshoe, is flat or plane on its underside, and is provided in its under side at the toe and heel with grooves20 to receive the upper ends of the threaded shanks of the calks 13.This foot-plate is placed between the bottom of the hoof and the heeland toe lugs of my adjustable clamp-horseshoe and is not permanentlysecured to the hoof in any manner, the adjustable clamp-horseshoeserving to secure the foot-plate in place and the latter forming anefficient bearing for the lugs, re-

movable calks, and the clamp-plates of the adjustable clamp-horseshoe.

It will be understood that my improved adjustable clamp-horseshoe may bereadily attached to a hoof over an ordinary shoe and used in connectiontherewith when the conditions require that a horse be sharp shod andthat the same may be removed When the conditions no longer exist.

Having thus described my invention, I claim-- 1.Ahorseshoe-clamphavingsidernemhers, each comprising a band portion tobear on the hoof, and downturned arms having their lower ends turnedinwardly to form toe and heel lugs to bear under the shoe, a rigid connectingplate to which the front portions of said side members areconnected, and clampplates detachably secured to the heel-lugs andhaving outturned flanges to bear on the upper side of the shoe,substantially as described.

2. Ahorseshoe-clampcomprisingsidememhers to bear on opposite sides of ahoof, and having inturned lugs, a rigid adjustable connection betweenthe front ends of the side members, a foot-plate to bear on thelugs andhaving vertical slots, and calks having screwshanks engaging threadedopenings in the lugs and coincident With the slots in the footplate,substantially as described.

3. Ahorseshoe-clampcomprisingsidemembers to bear on opposite sides of ahoof and having inturned lugs to bear under a shoe, near the toe andheel, in combination With means to connect the front ends of the sidemembers together, clamp-plates detachably secured to the heel-lugs andhaving outturned flanges bearing on'the upper side of the shoe, andcalks having screw shanks engaging threaded openingsin the heel-lugs andhearing against the under side of the shoe, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two Witnesses.

DAVID VESLEY BARR.
